I have spilled nutes on my plants many times and didnt notice it. The reason I say is because that doesn't resemble any disease or deficiency I have seen especially this early on. the plant wont be deficient from anything its too young. Is this your first grow?
how can it be deficient so young? if anything the first def you would see is nitrogen, yellowing bottom leaves. I know this looks like it could be cal mag but not so young IMO. When I first started growing I would germ with just PHed RO water up until week three with no Deficiencies. The seed has what it needs in terms of nutes to start life. He wouldn't see a cal mag def until weeks later. Just my experience. RO water has 0 TDS so that in theory should show a deficiency the fastest. I have never seen that on a plant of that age.
I grow hydro now and have used AN PH perfect. Still have some in stock. If you need help feel free to PM me. We need more specifics like are you using RO water or tap? city or well and the TDS of it.
Plants have enough energy to sprout. That's it. After that it relies on photosynthesis to live. In order for that the plant needs nutrients. In hydro that is very important because you are responsible for that. In soil nutrients are present usually for the plant to use for a couple weeks. Now in hydro deficiencies can pop up anytime. Even at a seedling stage. This is the most important stage of the plant. As the plant is trying to get established it is utilizing lots of different nutrients. Now I have never tried growing a seedling in a hydro set up but I think that could be hard on one. But yes a plant can have a deficiency at any time in its life. Even a seedling. Nitrogen is not the fist deficiency to always pop up in a seedling either. Especially if it's available. Ro water removes all calcium and magnesium and needs to be replace. Cannabis is a calcium whore.
he will have an established root system weather he grows from seed or clone. If he wants a more established root sytem he should use a
Adding bacteria to a hydro set up is useless. Bacteria and salt based nutrients don't mix. Furthermore it's not needed. Bacteria is used to break down nutrients so a plant can take them up. Liquid synthetic nutrients don't need to be broken down to be taken up by the roots. So there is no need for them. Plus they won't survive. Only products sold at hydro stores state that they do to sell it. Bacteria is for a soil web. But I guess you don't need to be schooled on that either.
Dude just stop you are clueless. I guess great white is BS then but marketed for hydro. You have no idea what you are talking about. Source please!
Actually gw has ecto and plenty of fluff that isn't useful for cannabis is any grow method. You are a fucking idiot if you think otherwise. Ecto is for trees not cannabis. A lot of shit is just that, marketed to cannabis growers. Doesn't make it right.
